Application July 3, 1944, Serial No..543,396

The invention relates to a combination lathe and drill press apparatuswhich is adapted to perform all of the functions of both machines.

The present invention is in the nature of an improvement over thegeneral construction shown in my prior Patent 2,226,029 for aLathe-Drill Press, granted December 24, 1940, and involvessimplifications and improvements which result in a much better machineand which can be constructed and operated more economically.

It is one of the objects of the invention to provide a combination latheand drill press wherein the lathe bed serves as a support for the motorat one end and the head stock at the other end so that onecounterbalances the other in manipulating the bed.

Another object of the invention is to provide a, combination lathe anddrill press wherein the lathe bed serves as a support and housing forthe drive shaft from the motor to the head stock.

Still another object of the invention is to provide a combination latheand drill press wherein the equipment which is movable is generallybalanced so as to permit convenient manipulation thereof while providingan equipment which will operate satisfactorily both as a lathe and as adrill press.

Another object of the invention is to provide a combination tail stockand drill press table which is reversible and which can be utilized withthe machine for either purpose.

Still another object of the invention is to provide a motor drivenlathe-drill press wherein the motor serves as a counterbalance for thelathe bed and head stock.

Other and further objects of the invention will be readily apparent whenthe following description is considered in connection with theaccompaying drawings wherein:

Fig. 1 is a side elevation of the apparatus in position for use as alathe.

Fig. 2 is a top plan view looking down on the apparatus of Fig. 1-.

Fig. 3 is a vertical sectional view through the tubular lathe bed andillustrating the manner of mounting the drive shaft therein.

Fig. 4 is a section taken on the line 4-4 of Fig. 3 to illustrate thearrangement of one of the shaft bearings positioned in the tubular lathebed.

Fig. 5 is a front face view of the tail stockand table.

Fig. 6 is a vertical sectional view taken on the line 6-6 of Fig. 5.

Fig 7. is an end elevation of the mounting for pivoting the lathe bed.

1 Claim. (01. 308-26) Fig. 8 is a side elevation withthe equipmenttilted to a vertical position for use as a drill press.

In Fig. 1 a bench 2 has been illustrated as hav-. ing a top 3, legs 4and bracing 5. The two legs at the right hand end are provided with lugsor brackets 6 which project-therefrom and act as.a support for the pivotyoke 8 which is arranged to support the lathe bed Ill.

This pivot yoke is seen in end elevation in Fig. 7 and includes the twolegs I I, each of which carries a pivot bolt I2 to be fastened to thelugs 6. The sleeve [3 is formed on the cross brace I4 and is of thesplit type so that it. may be adjusted by means of a clamping bolt l5 inorder to grip. or release the tubular lathe bed [0. i

As seen in Fig. 3 the lathe bed' ID is a hollowi tubular member having.an end plug I! which is arranged to be threaded at l8 into the end ofthe tube. This 111g is formed with the motor support, arms l9 thereon sothat a motor 20 may be pivoted at 2| to the arms. In order to adjustthe. position of the. motor relative to the lathe bed In the links 22have been provided and are con-.- nected to the bar 23-fixed to themotor and havea slot 24 which is adjustable on a bolt 25 carried; by thearms I9. This adjustment permits tightening orloosening of the belt 21which passes over the sheave -28 of the motor and the sheave 29 on thedrive shaft 30 which is mounted forrotation in the end plug l1. r

The end plug IT carries abearing 3! so as to re.- tatably support theshaft 30. This bearing is ofspeoial construction in that it has theanti-frie tional bearings'tlwhich are enclosed by a res1lient packing 33held in position by a gland 34 afiixed to the shaft by screws 35. Alubricant fitting 3B is arranged to supply lubricant to' the bearing. 1i

As seen in the drawing the shaft 30 willbe of considerable length soasto extend through the lathe bed I U" and the intermediate bearings38are therefore provided. These bearings are of special construction to beanchored inside of the tube: and include a bearing sleeve 39 having theendplates 40 in the form of annular discs slipped over;

the sleeve to fit slidablyagainst the sleeve and against the innerperiphery 4! of the tube-l0.

Disposed between these plates, however,.is an.

It seems obvious that bolts 43 screwed home so as to pull the two platestogether and expand the resilient ring 42 so as to frictionally engagethe inside of the housing. In this manner the bearing is adapted toabsorb a certain amount of vibration and will be suitably anchoredinside of the tube. Two such bearings are shown and then the head stockend bearing 41 serves to support the other end of the shaft.

This bearing includes the anti-friction portion sition by the crossbolts 55 best seen in Fig. 1.

This head stock carries the head stock arbor 56 which is rotatablymounted therein in a suitable bearing structure which supports the headstock pulley 51. These pulleys are arranged to be driven by the sheaves58 mounted on the head stock end of the shaft 30 and the power istransmittedby a belt 59.

"In order to clamp'the lathe bed in lathe op erating position as seen inFig. 1 a foot 60 is shown as fixed to the headstock housing 52 whichfoot is arranged to engage under the plate 61 fixed by the screws 62 onthe bench 2. This foot is slipped under the plate by releasing the clampI3 and sliding the bed tube H) to the left as seen in Fig. 1. The clampI3 is then again tightened by the lock arm andbolt 15 so that the bed issecurely clamped in the position of Fig. 1. A switch 65 for control ofthe motor is shown on the right hand end of the bench 2 in Fig. 1, butinasmuch as the operator is usually toward the left hand end of thebench when using the machine as a lathe, a switch rod 66 has beenmounted in the eyes -61 on the side of the bench.

The lathe bed I serves a dual purpose,-that of supporting and carryingthe bearings for the drive shaft 30 and also for supporting the toolrest support sleeve 58. This sleeve is arranged to be tightenedor'loosened relative to the tubular bed by means of a clamp bolt 69.This tool rest sleeve carries the tool rest slide 10 which in turncarriesthe lockingbolt 1| in order to clamp the tool rest 12 inposition.

The lathe bed I0 also supports the tail stock sleeve 14 which can beclamped in desired position by the bolts 15. A centering adjustmentdevice 16 is carried by the sleeve and the upper portion of the tailstock is arranged to support the'tail stock quill 18. This constructionis best seen in section in Fig. '6 where the tail stock quill is shownas having a rack 19 thereon operable by the pinion 80 and the hand wheelBl so as to adjust the quill to and fro. The quill, it will be observed,has a morse taper area 8| at each end thereof so that the quill may bereversed and either end may be used as desired. A morse dead centre 82is shown as disposed in the left hand end of the quill. The quill isthreaded at 83 to receive the table 84 which is arranged to receivevarious types of blocks, chucks or supports for various pieces ofequipment or the work. The table is shown as having a pair of extensions85 thereon which are arranged to partially embrace the lathe bed I0 andto be slidably adjusted, never clamped, thereto'by means of a bolt 86.

Fig. '8 shows the machine tilted from the horizontal lathe position ofFig. 1 to'the vertical drill press position by-merely releasing theclamp bolt 15, sliding assembly to the right, then tightening the bolt land tilting the bed I0. The particu- 4 lar advantage of the arrangementof the motor 20 on one end of the lathe bed and the head stock on theother end of the bed is now apparent because each counterbalances theother in order to permit the ready tilting of the bed from vertical tohorizontal position. To accomplish this tilting operation it is onlynecessary to release the bolt 15 and the clamp sleeve 13 so that thetube 10 may slide therein. When such release is accomplished then theentire bed including the head stock can be moved to the right as seen inFig. 1. This moves the foot 60 from beneath the plate 6!. The bed isthen moved to the right a suificient distance so that when locked by 15and then tilted up, the end of the bed will barely clear the socketwhich is disposed on the floor as best seen in Fig. 1. This socket has acup 9| therein so as to engage the ball 94 carried :by the yoke 95 fixedon the end of the bed by the bolts 96. A lever '92 pivoted at 93 isprovided to lift the ball 9 out of the cup to permit tilting back tolathe position. After sliding the assembly to the right, before thetilting action, the clamp 13 should be tightened and the bed tilted andthen the clamp released so as to allow the tube to slide down a shortdistance into the cup 9| so as to properly center the entire piece ofequipment. The clamp can be again tightened and the tools and variousparts are now locked in position for use as a drill press. The arbor 56is arranged to receive morse taper tools or threaded chucks or otherequipment and the tool rest sleeve 68 may or may not be used. The sideof the tube or lathe bed 10 may have a groove 97 therein a best seen inFigs. 1 and 8 so as to hold the various equipment in a vertical planeregardless of whether the bed is being used as a lathe or drill press.

Broad-1y the invention contemplates a combination lathe and drill presswherein the parts are balanced and the motor and the head stock tend tobalance each other.

What is claimed is:

In a combination lathe and drill press a bed comprising a tubularmember, a drive shaft therein, bearings for said shaft mounted in saidmember, each of said bearings including a shaft support portion, a pairof end support plates fitting said portion and the inside of saidtubular member, a resilient member disposed between said plates, andmeans to draw said plates together to force said member against theinside of said tube to anchor said bearing.
